I have a 95 chevy blazer LS, approx 170,000 miles I cannot get it to start. It is one of the "w" vin codes, and has the OBD II system in it. It turns over and gets spark, I have put a new fuel filter in, a new fuel pump, a new fuel relay, and a new EGR valve($175). And it still will not start the fuel pressure is good. It has A CMFI fuel injection system. If we prime the engine it will start and then die. Any Ideas as to what my problem could be. When it died I had just come back from about a 150 mile drive and come around a corner and it died like it was starving for fuel. What should I check next?

Humm Pull the plugs, put oil in all the culinders, spin the engine, put in a little more oil, spin the engine. Replace the plugs. It sounds like you might have washed the cyls with gas causing very low compression.

These s-10's, and s-15's, always have this issue. I've had it myself, check your fuse box. There should be a fuse labeled ECM, or ECM1. Check it, then replace. Replace it anyways. Should be a 15 amp.
THis fixed my problem. Same one your having. Then, I found out that my oil sending unit was on it's way out. It was shorting out that particular fuse. I just unpluged the the wire connection at my sending unit. And it fired right up. The only other thing I think can cause this would be the modual in the distributor. But I would go with the fuse. Good luck
